Black Jack, known as the “Surgeon with the Hands of God,” is a mysterious young Japanese doctor who travels the world performing miraculous surgical feats. While everyone admires his extraordinary skill, he is widely despised, particularly by the medical establishment, because he refuses to obey any rules and charges exorbitant fees for his services. His only companion is Pinoko, a child he created from a special tumor called a teratoma, who insists that she is his wife.
